can use a library created in vb.net or c# in java?

Question

I have written some classes in C# and compiled it. Now I have the library file for these classes. Can I use the same dll with Java?

I do not want to write it in Java once again because I am writing the same program in different languages (trying to do so).

So I am making the classes to a library file and want to use it in all the programing languages.

Answer 1

Java normally uses a completely different runtime (inside the JVM). There are tools intending to help bridge the gap ( IKVM leaps to mind), but in general : no, you can't do this. Of course, you can use IPC etc to talk between them, but they are not best friends.

Answer 2

You need to searialize your code into byte, xml or json. so you can use your codes in another language

Answer 3

One area you can look into is JNI (Java Native Interface), see http://en.wikipedia.org/wiki/Java_Native_Interface as a starting point. There are possibly easier to use bridges for .NET to Java, ah here we go, see Calling C# code from Java?
